‘Pueblo’ is a new pecan (Carya illinoinensis) cultivar released and patented by the U.S. Department of Agriculture, Agricultural Research Service (USDA ARS). This cultivar is the first to be released with a compact tree size, great precocity, early nut maturation, high yield potential, and scab resistance. ‘Pueblo’ should perform well in the West, central Texas, and as far north as southeastern Kansas. ‘Pueblo’ is the first of three patented pecan cultivars in the USDA ARS Pecan Breeding Program (U.S. Patent Application Serial No. 17/506,091). Parties interested in licensing ‘Pueblo’ should contact firstname.lastname@example.org with any questions. Graft wood will only be distributed to licensees.
The USDA ARS Pecan Breeding and Genetics Program conducts the only national pecan breeding program and releases control-crossed superior pecan cultivars to nurseries and growers (Grauke, 2019; Grauke et al., 2016; Thompson et al., 2008; Thompson and Grauke, 1991). Crosses are made in both Brownwood and Somerville in Texas. Seedlings are established on their own roots in a basic breeding program (BBP) orchard for the initial testing of growth, disease, flowering, nut yields, and nut quality. Promising seedlings are then advanced to the National Pecan Advanced Clone Testing System (NPACTS). In NPACTS, five to six grafted replicates of promising seedlings (≈25–30) are arranged in a randomized block with three to five commercial varieties serving as controls for comparisons across multiple years. The superior clones with unique traits are given Native American tribe names and released to nurseries and growers.
‘Pueblo’ is the first of three patented pecan cultivars by the USDA ARS (U.S. Patent Application Serial No. 17/506,091) (Grauke et al., 2021; Wang et al., 2022). The Pueblo are a group of Native American tribes in the Southwestern United States set apart from their indigenous neighbors by two main criteria: farming as their primary form of subsistence and residence in compact villages (Dozier, 1964). The compact tree shape of ‘Pueblo’ and recommendation for it to be grown in the West (among other areas) inspired the selection of its name.
